Suggested definition of 'differences' to be shown by tuneDisplay for various devices:
|
|
|
|
|
|
* Quads (both magnetic and electrostatic): The percent difference between the quad's calculated setpoint (current or voltage) ($`SP_{theo}`$) and its actual setpoint ($`SP_{act}`$).
|
|
|
* Quads (both magnetic and electrostatic): The percent difference between the quad's calculated setpoint (current or voltage) ($`{SP}_{theo}`$) and its actual setpoint ($`{SP}_{act}`$).
|
|
|
```math
|
|
|
\Delta = \frac{100 \cdot \left( SP_{act} - SP_{theo}\right)}{SP_{theo}}
|
|
|
\Delta = \frac{100 \cdot \left( {SP}_{act} - {SP}_{theo}\right)}{{SP}_{theo}}
|
|
|
```
|
|
|
|
|
|
* Electrostatic steerers: the difference will be the actual steering voltage (steerer setpoint minus common plate setpoint) minus the calculated steering voltage (steerer setpoint minus common plate setpoint), divided by the the full scale of the steerer supply (1000 V for most steerers in ISAC), multiplied by the maximum source voltage over the actual source voltage.
|
|
|
* Electrostatic steerers: the difference will be the actual steering voltage (steerer setpoint minus common plate setpoint) ($`U_{act}`$) minus the calculated steering voltage (steerer setpoint minus common plate setpoint) ($`U_{theo}`$), divided by the the full scale of the steerer supply (1000 V for most steerers in ISAC) ($`\DeltaU`$), multiplied by the maximum source voltage ($`U_{max, source}`$) over the actual source voltage ($`U_{act, source}`$).
|
|
|
```math
|
|
|
\Delta = \frac{100 \cdot \left( U_{act} - U_{theo}\right)}{\DeltaU} \cdot frac{U_{max, source}}{U_{act, source}}
|
|
|
```
|
|
|
`Diff = 100*[(actual_steering - calc_steering)/steerer_range]*(max_source_vol/actual_source_vol)`
|
|
|
For a typical ISAC electrostatic steerer this becomes:
|
|
|
`Diff = 100*[(actual_steering - calc_steering)/1000]*(60/actual_source_vol)`
|
|
|
```math
|
|
|
\Delta = \frac{100 \cdot \left( U_{act} - U_{theo}\right)}{1000} \cdot frac{60}{U_{act, source}}
|
|
|
```
|
|
|
`Diff = 100*[(actual_steering - calc_steering)/1000]*(60/actual_source_vol)`
|
|
|
|
|
|
* Magnetic steerers: the difference will be the actual steerer current minus the calculated steerer current, divided by the the full scale of the steerer supply (6 A or 200 A for most steerers in ISAC), multiplied by the maximum beam rigidity (Bp) at that location over the actual beam rigidity (Bp).
|
|
|
```math
|
|
|
\Delta = \frac{100 \cdot \left( U_{act} - U_{theo}\right)}{\DeltaU} \cdot frac{U_{max, source}}{U_{act, source}}
|
|
|
```
|
|
|
`Diff = 100*[(actual_setpoint - calc_setpoint)/steerer_range]*(max_Bp/actual_Bp)`
|
|
|
For a typical 100 A ISAC magnetic steerer in MEBT this becomes:
|
|
|
```math
|
|
|
\Delta = \frac{100 \cdot \left( U_{act} - U_{theo}\right)}{1000} \cdot frac{60}{U_{act, source}}
|
|
|
```
|
|
|
`Diff = 100*[(actual_setpoint - calc_setpoint)/200]*(1700 kG*cm/actual_Bp)`
|
|
|
|
|
|
* Magnetic dipoles: The percent difference between the dipole's calculated field setpoint (gauss) and its actual setpoint `Diff = 100*(actual_setpoint - calc_setpoint)/calc_setpoint`
|
|
|
* Magnetic dipoles: The percent difference between the dipole's calculated field setpoint (Gauss) ($`B_{theo}`$) and its actual setpoint ($`B_{act}`$).
|
|
|
```math
|
|
|
\Delta = \frac{100 \cdot \left( B_{act} - B_{theo}\right)}{B_{theo}}
|
|
|
```
|
|
|
|
|
|
* RF phases: The difference between the calculated phase setpoint (in degrees) and its actual setpoint, normalized to 180 degrees `Diff = 100*(actual_setpoint - calc_setpoint)/180`
|
|
|
* RF phases: The difference between the calculated phase setpoint (in degrees) ($`\varphi_{theo}`$) and its actual setpoint ($`\varphi_{act}`$), normalized to 180 degrees.
|
|
|
```math
|
|
|
\Delta = \frac{100 \cdot \left( A_{act} - A_{theo}\right)}{A_{theo}}
|
|
|
```
|
|
|
|
|
|
* RF amplitudes: The percent difference between the calculated amplitude setpoint (units unspecified) and its actual setpoint. `Diff = 100*(actual_setpoint - calc_setpoint)/calc_setpoint` |
